Description

Technical Field

[0001] This utility model relates to the field of stove burner technology, and in particular to a sheet metal burner that can be quickly positioned. Background Technology

[0002] In recent years, with the improvement of stainless steel processing technology, its excellent surface finish, high melting point, strong oxidation resistance, and good mechanical properties have gradually gained favor. Using stainless steel to manufacture burners has become an important development direction in the industry. Stainless steel burners not only have a long lifespan and beautiful appearance, but also better meet clean production standards. For example, patent CN202122777870.8 proposes a sheet metal stamping burner head structure. This structure omits the traditional gas mixing chamber, relying solely on the main injector and central injector to directly connect to the gas distribution plate. While this reduces material and manufacturing costs to some extent, the entire sheet metal burner head is composed of sheet metal parts assembled from multiple sheet metal components, lacking versatility. Two-ring burners have a relatively high market share due to their low cost. Their burner heads typically include two independent injectors, arranged in a coaxial nested or staggered configuration. For products with staggered arrangement of the two injectors in the burner head, the positioning structure of the outer ring burner needs to be considered due to the staggered arrangement of the air inlet pipes of the central burner cap and the outer ring burner cap. When using sheet metal burners, it is necessary to consider both the need for a simple sheet metal burner and the requirement for quick positioning. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a sheet metal burner that can be quickly positioned.

[0004] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a sheet metal burner that can be quickly positioned, comprising: a sheet metal formed flame distribution plate, a flame cap, an air inlet cylinder and a positioning seat; The flame distribution plate and the flame cap are circular in shape. The flame cap is placed above the flame distribution plate and surrounds the flame distribution plate to form a ring-shaped mixing chamber. The flame cap has several flame outlet holes. The flame distribution plate has positioning holes and air inlets. The air inlet cylinder has a vertically continuous cylindrical structure, with its upper end riveted to the air inlet hole for connecting to the outer ring ejector tube of the burner head. The positioning seat has a bowl-shaped structure with an opening at the top, and its upper part is riveted to the positioning hole. The bottom of the positioning seat has an upwardly recessed positioning recess for positioning in conjunction with the positioning components of the burner head.

[0005] Optionally, the positioning holes and positioning seats are provided in two sets, and the two positioning holes and air inlets are staggered.

[0006] Optionally, the positioning seat has a frustum-shaped structure with the lower component narrowing.

[0007] Optionally, the flame distribution plate is welded with a gas distribution plate, which has a fan-shaped structure and has several gas distribution holes, which are spaced apart above the air inlet.

[0008] Optionally, the outer ring wall of the flame cap is provided with an overlapping ring platform to overlap and be fitted over the flame distribution plate.

[0009] The beneficial effects of this utility model are as follows: By using sheet metal-formed burner discs, burner caps, air inlet cylinders, and positioning seats, lightweight and low-cost manufacturing of the burner structure is achieved, fully utilizing the advantages of stainless steel material such as high temperature resistance, corrosion resistance, and ease of stamping. The burner cap and burner disc form an annular mixing chamber, with a compact structure that effectively ensures the premixing effect of gas and air, resulting in more complete and stable combustion. The positioning seat is designed as a bowl-shaped structure with an open top, and its positioning recess at the bottom cooperates with the positioning parts on the burner head, enabling quick and accurate positioning of the burner during installation. This greatly simplifies the assembly process, improves production efficiency and installation consistency, and avoids reduced combustion efficiency or safety hazards caused by misalignment during use.

[0017] Example Reference Figures 1 to 3 The present invention proposes a sheet metal burner that can be quickly positioned, comprising: a sheet metal forming flame distribution plate 10, a flame cap 20, an air inlet cylinder 30, and a positioning seat 40. The fire distribution plate 10 and the flame cover 20 are in a ring shape. The flame cover 20 is placed above the fire distribution plate 10 and surrounds the fire distribution plate 10 to form a ring-shaped mixing chamber. The flame cover 20 has several flame outlet holes. The fire distribution plate 10 has a positioning hole 11 and an air inlet hole 12. The air inlet cylinder 30 has a cylindrical structure that runs vertically through the top and bottom. The upper end is riveted to the air inlet hole 12 and is used to connect to the outer ring ejector tube of the burner head. The positioning seat 40 has a bowl-shaped structure with an opening at the top and is riveted to the positioning hole 11 at the top. The bottom of the positioning seat 40 has an upwardly recessed positioning recess 41, which is used to cooperate with the positioning parts of the burner head for positioning.

[0018] In this invention, the use of sheet metal-formed flame distribution plate 10, flame cap 20, air inlet cylinder 30, and positioning seat 40 achieves lightweight and low-cost manufacturing of the burner structure, fully utilizing the advantages of stainless steel material such as high temperature resistance, corrosion resistance, and ease of stamping. The flame cap 20 and flame distribution plate 10 form an annular mixing chamber, with a compact structure that effectively ensures the premixing effect of gas and air, resulting in more complete and stable combustion. The positioning seat 40 is designed as a bowl-shaped structure with an open top, and its positioning recess 41 at the bottom cooperates with the positioning parts on the burner head, enabling quick and accurate positioning of the burner during installation. This greatly simplifies the assembly process, improves production efficiency and installation consistency, and avoids reduced combustion efficiency or safety hazards caused by misalignment during use.

[0019] In this embodiment, two sets of positioning holes 11 and positioning seats 40 are provided, with the two positioning holes 11 and the air inlet 12 arranged in a staggered manner. The two sets of staggered positioning holes 11 and positioning seats 40 form a stable multi-point positioning support structure. This design effectively enhances the stability of the burner installation on the furnace head, preventing it from shifting or rotating due to vibration or airflow impact during operation, thus ensuring the long-term reliability of the combustion process.

[0020] Specifically, the positioning seat 40 has a frustum-shaped structure that narrows at the bottom. The frustum-shaped structure of the positioning seat 40, which narrows at the bottom, provides good guidance and reduces the volume occupied in the lower part of the positioning seat 40.

[0021] In this embodiment, the burner plate 10 is welded with a gas distribution plate 50. The gas distribution plate 50 has a fan-shaped structure and several gas distribution holes, which are spaced above the air inlet 12. The fan-shaped gas distribution plate 50 with gas distribution holes welded onto the burner plate 10 and spaced above the air inlet 12 can effectively divide and distribute the gas entering from the air inlet cylinder 30. This ensures that the gas can enter all parts of the annular mixing chamber more evenly, thereby making the flame output of the burner cap 20 more uniform, effectively improving combustion efficiency and avoiding local high temperature, and extending the service life of the burner.

[0022] In this embodiment, the outer annular wall of the burner cap 20 is provided with an overlapping ring platform 21 to overlap and fit over the ignition plate 10. The overlapping ring platform 21 on the outer annular wall of the burner cap 20 allows it to be precisely fitted and overlapped over the ignition plate 10. This structure not only enables rapid and accurate alignment and assembly of the burner cap 20 and the ignition plate 10, but also enhances the sealing of the joint, effectively preventing gas leakage in the mixing chamber and ensuring safe operation. Simultaneously, this overlapping structure is stable and reliable, and facilitates disassembly, cleaning, or maintenance.

[0023] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
